GEORGE K. RIX, OF CHICAGO, ILDINOIS.

SMOKING-PIPE.

SPECIFICATION forming part of Letters Patent No. 224,107, dated February 3, 1880.

Application filed February 5, 1879.

To all whom it may concern. Be it known that I, GEORGE K. RIX, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Smoking-Pipes; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to the provision in the bowl of a tobacco-pipe of a diaphragm of fine wire-cloth in position to permit the air drawn through the stem to pass equally through all portions of the tobacco mass, and also to prevent the tobacco from falling into the bottom of the bowl, either to become soaked by the moisture there likely to accumulate or to enter or obstruct the stem.

It consists, as hereinafter fully explained, in providing a ledge within the bowl, upon which, by its margin, the diaphragm rests,

and in firmly holding the diaphragm upon such ledge by screwing the upper detachable portion of the bowl down upon it, with other features, as set forth, and pointed out in the claim.

The drawing illustrates a pipe having my improvement in vertical section of the bowl and aportion of the stem.

The bowl consists of two parts, A and B, horizontally joined at a 1), near the insertion of the stem 0. The lower portion has the chamber D, communicating with the stem in the usual manner. At the top this chamber is enlarged, so as to give the horizontal annular ledge c. The upper portion is reduced to fit said enlargement and give the close joint a b, both parts being threaded to screw firmly and tightly together, as shown. Resting on the ledge c, and firmly clasped at its margin between A and B, is a disk, d, of fine wire'cloth, serving as a diaphragm to completely prevent the passage of particles of tobacco from the upper to the lower chamber of the bowl, while freely allowing the air and smoke to be drawn through it.

The apertures being equally distributed over the entire area of the diaphragm, the draft is equal at all points of the burning surface, whereby the tobacco is made to burn down uniformly in all parts of the bowl. Moreover, being supported above the moisture that invariably accumulates at the bottom of the bowl in smoking, the entire body of tobacco may be consumed. Whether it be smoked out or not, the bowl will be completelyeinptied of its contents above the diaphragm with much less trouble than if without the disk, since there is no moisture in the same to cause adhesion and no apertures large enough to admit any portion of broken tobacco.

To further insure these results the upper portion of the bowl, at the point where it rests upon the disk, shelves ,over the ledge c, as clearly seen at e in the drawing, so that the downward air-draft is free throughout the entire area of the tobacco-base, tending to its more perfect and complete consumption, and affording no lodgingplace for moisture induced by combustion.

Anotheradvantageoftheshelvingproiection e, as described, is that when the pipe is laid aside in smoking, any water accumulated in the lower chamber will be arrested by the projection and prevented from entering the tobacco or running out of the bowl.

After smoking, it will be occasionally necessary to empty the lower chamber, D, which is easily done by unscrewing the parts of the bowl, and lifting the disk. After cleaning, the disk is quickly replaced and secured, as before.

No niaterial will be quite so favorable to the free discharge of the upper bowl as fine wire-cloth, in which the apertures are much smaller than they can well be punctured in a metal plate. However, a punctured plate will serve, and when used is much more effective and easily managed if secured in the bowl in the manner described.

The'wire-cloth should be tinned or metalplated to prevent corrosion.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
